Abstract: A needle 1 for penetrating a membrane 2, having a pointed end 3 provided with a penetrating tip 4 and with an opening 6 for letting a liquid in and/or out in a main direction 7 which is substantially parallel to the longitudinal extension of the needle 1. The penetrating tip 4 is designed with a substantially point-shaped edge 8 to initially prick the membrane when the membrane is penetrated. The outer edges 19 present on the pointed end 3 in the area from the point-shaped edge 8 to a position beyond the opening 6 are rounded so that after the initial penetration the pointed end 3 will push the membrane material away rather than cutting the membrane material.

Abstract: Medical cannulas are typically provided with a silicone coating to improve incision performance. In order to produce a thin, continuous and even coating layer, silicone oil is provided at one side of an elastic foil and the foil is penetrated by the uncoated cannula from an opposite side. During this operation the cannula is wetted by the silicone oil. During withdrawal of the cannula from the foil, excess silicone oil is removed from the cannula and an even, particle-free thin coating which has no bulge- or bead-forming tendency during incision is obtained. Subsequently, the silicone coating is dried.

Abstract: A hair drier hood is formed of an approximately sickle shaped laterally open cap (1) and a pair of arms (4, 5) located on the opposite sides of the cap. Each of said arm has a heating element (12), and a plurality of spaced apart heating elements (8) are located in the cap. A box shaped projection (2) is located at the end of the cap arranged to be located adjacent the neck of a person. A blower (13) is positioned in the projection (2) and arranged to direct air into the cap. In the cap (1) the heating elements (8) are separated from ducts (15, 16) by a reflector (10). The reflector (10) contain air outlet orifices (9) spaced apart along the cap. Air is directed through the ducts (15, 16) along the length of the cap (1) and passes through the air outlet orifices (9) and toward the head of the person using the drier.

Abstract: An injection device can be loaded by the user only when in the zero position. This reminds even forgetful patients to readjust the dose before the injection and is of great help to blind patients.
